Ideally, that would be the case, but in reality, it doesn’t work that way.Sorry if I'm missing the point, but I though it was only applied to the opposite ear! It just has to be done over and over again because both ears pick up the correcting signal, unless a local wearable device was used right at each ear to correct the crosstalk. But in this case, if it worked perfectly, then still the opposite ear would hear nothing from that channel, so it'd just be simpler because the correction signal would not have to be recursive. I still think we have to find a way to reduce the effect as sounds are panned further left or right.
The sound comes from the left speaker, and the left ear hears it first. Then, after the ITD, the right ear hears it.
At this point, the right speaker sends out a cancellation signal for it. While this signal cancels the sound for the right ear, the left ear also hears the cancellation signal.
That’s why repeated signals are cross-fed to erase unintended traces.
The graph I shared shows the results of applying a filter that specifically targets only the opposite ear. (Of course, this isn’t possible in reality.)
This is a bit off-topic, but I have almost implemented Dolby Pro Logic IIX using EQ APO (excluding dynamic steering, as EQ APO cannot utilize real-time level detection to assign weights, so it would need to be re-created in Reaper).similar to what Dolby Pro-Logic up-mixing does.
While working on this, I also started studying Logic7, which many people seemed to appreciate.
I recall reading some documents about the Lexicon DC-1 and noticing that it also had a form of crosstalk cancellation hidden within it.
